provide an improved form of sofa bed of the type in which a plurality ofalternate wide and narrow sections are pivotally connected frame to forma sofa, or to behorizontally extended to form a bed; to provide immproved mechanism for locking certain of' said sections together in theirfolded posi-.

tions; and to provide improvedmeans for operating said lockingmechanism.

An illustrative embodiment of this inven tion is shown in theaccompanying drawings, in which Figure 1 is a plan view of the sofa bedwith the sections extended to form a bed,

parts thereof being broken away or omitted. partly sectional, of

Fig. 2 is a side elevation, the sofa bed with the be sections in theirfolded positions and the seat inverted. Fig.

3 is aside elevation of the sofa bed with thebed sections extended.Fig.- 4 is an enlarged sectional elevation'of the operating means forthe locking mechanism as viewed from the plane of the line AA.of Fig. 1.Fig. 5 is a fragmentary end view of the parts shown in Fig. 1. Fig. 6 isa side elevation of the bed sections with the outer wide section foldedonto the middle wide section. v p

In the construction shown in the drawings, the sofa bed comprises theusual frame, having a back 1 and ends 2 on which is the sofa seat 3.Plates 4 and 5 are respectively supported on the ends 2 of the frame andthe ends of the seat 3, and have coacting pins and slots by means ofwhich the seat is adapted to be revolved from a sofa position to aninverted position to permit the unfolding of the bed sections carriedthereby. The bed sections, of which there are the inner wide section 6,middle wide section 7, outer wide section 8, and intermediate narrowsections 9 and 10, are supported onthe under side of the sofa seat 3 bymeans ofthe brackets 11. The narrow section 9 is provided with pins 12which are secured to the brackets 11, and which pivotally support thesection so that it may be turned from a transverse position with respectto said wide sections to a horizontally alinedposition. The inner widesection 6. is provided with pins 13 which coact with the camplates 14for elevating the section into horizontalalinement with the otherbed'section's when they are extended. The locking mechanism for securingthe outer wide section 8 tothe middle wide section 7 in their foldedpositions comprises latch members or plates 15 piv p otally mounted at16' at the sides of the duter together so as to be folded into asupporting wide section 8, adjacent to the corners thereretractedposition at the sides of the bed section 8- when the sectionsareextended, and occupy a position transversc'thereto when the sectionsare folded so' that the notches 17 will engage the pins '18. a Themechanism for shifting the latch members 15 from one to the other ofthese positions comprises a shaft or rod 19 pivotally mounted in thebearings 20 at the sides of the section 8, and having transverselydisposed arms 21 extending upwardly from the ends thereof. Outwardlydisposed shoulders 22 are formed on the ends of the arms 21 and arereceived in slots 23 in the angularly disposed extensions 24 integrallyformed on the members 15. The shaft or rod 19 extends across the end ofthe outer bed section 8 and near the middle is bent upwardly to form anarm 25 and downwardly to form another arm or .extension 26, The shaft 19together with the arms 21 and 25 .forms a crank which is adapted to beoperated by the foot rest 28. The foot rest- 28 is pivotally mounted onthe bar 29 extending across the. end of the wide section 8 and near themiddle is provided with a depending-fork 27 which engages the arm 25 onthe shaft 19. The foot rest is adapted to be shifted from asubstantially parallel position with respect to said section, when saidbed sections are folded, to a transverse position when said sections areextended. When so shifted the shaft 19 is partially rotated whereby themembers 15 are also shifted by reason of the connection of the arms 21.The arm 26 is provided for the purpose of retracting the latch members asufficient distance to disengage the pins 18 when it is not convenient.to operate the members 15 by means of the foot rest 28. The middlesection 7 is supported in its extended posit-ion by means of a leg 30which is operated by a link 31, and the outer section 8 is supported bya leg 32 operated by a link 33.

The operation of the device is as follows: When it isdesired to convertthe sofa bed from a bed to a sofa, the foot rest 28 is first shiftedfrom a vertical position down onto the mattress and bedding. Thismovement of the foot rest causes the fork 27 operating on the arm torotate the shaft 19 whereby the latch members 15 are shifted from theirretracted positions into vertically disposed positions transversely ofthe bed section. As the outermost section 8 is then folded over onto themiddle wide section, the members 15 strike the pins 18 and cause them toenter into engagement with the slots 17 whereby the bed sections arelocked together as shown in Fig. 6. The sections are then folded overonto the seat frame where they may be locked thereto in any desiredmanner. The seat 3 is then revolved into its normal position withrespect to the frame, so that it may be used as a sofa. When it isdesired to unlock the bed sections 7 and 8 in converting the sofa bedinto a bed, the operator lifts the arm 26 so as to give a partialrotation to the shaft 19 and cause the latch members 15 to be retractedfrom the pins 18 and permit the bed section 8 to be shifted to itshorizontal osition. The foot rest 28 is then shifted to its verticalposition, which causes the fork 27 to rotate the shaft 19 andcausethe-arms 21 to.

retract the members 15 into positions at the sides of the outer bedsection 8.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as defined by the following claims.
